November 23rd - Doctor Who's 14th Birthday
November 27th - Verity Lambert's 42nd Birthday
December 16th - Nicholas Courtney's 48th Birthday
I don't think I ever realised how young Verity Lambert was. I thought she was mid 30s when the show began. Makes her accomplishments on the show even more of an achievement when you consider her age as well
She was virtually untried - that's why they gave her an executive producer for her first series, as they did later with JNT.
